As computational chemistry tools have developed over the last decade or so, molecular graphics and visualization have played a prominent role in expressing complex three-and higher-dimensional properties of molecules, such as, e.g., wavefunctions. Just as structured languages such as HTML and its incorporation of URL descriptors were used to achieve structure and context for text-based documents, so there came a realization that a three-dimensional object description language was needed to express the context in more complex 3D scenes, or worlds as they became known. 

Virtual reality modeling language is a file format for the description of 3D objects based on the Open Inventor file format. 

For implementation of the model an object oriented approach based on the programming language C++ has been chosen. The authors developed the software library TOSCA (tools of object oriented software for continuum mechanics application) [8] which provides all classes required for description of continuum mechanics problems, as e.g. numerical solvers, discretization methods and data bases...
